Answer 2

Assuming you mean width and height you would do:

$img = imagecreatefromjpeg("img.jpg");
$w = imagesx($img);
$h = imagesy($img);

EDIT: if you want to know where an image is on the screen that is not a job for PHP but for a client-side language, like JavaScript

Answer 3

如果您在谈论图像尺寸， getimagesize()函数适合您！
